Exposure is the total amount of light allowed to fall on a sensor or film during the taking of a photograph. This is determined by the exposure time (shutter speed) and amount of light admitted (lens aperture). Today, sensor/film sensitivity (ISO speed) is often also considered to be part of ...

I realize that an image histogram is a graphical display of an images tonal distribution (i.e. horizontal darks to lights, vertical pixel distribution), but how does one really use it and why? I mean, ...

I'm shooting towards the sky to capture the stars. The exposure time is 15 seconds, so I can see the stars still, without a trace. These photos are taken continuously one after the other, because I ...

The more I read about this, the more confused I become. Illuminance, as I understand it, measured in lux, is the perceived brightness of light on a surface. It's what you'd measure with an incident ...

I have found myself using spot metering on several occasions in order to get the right exposure, such as sunsets and on bright days with a subject in the shade. What other situations are well suited ...

I have a Canon XTI which I've been using for a few years now. Most of the time I'm been shooting in one of the "semi-manual" modes like aperture priority or shutter priority, but now I'd like to try ...

I know there is already a question about EV, but it doens't quite answer my question. I understand EV as a relative measurement, 1 EV being one stop (doubling or halving the amount of light), but what ...

I have read the existing question - Does the camera white balance setting affect the raw image at all?
After reading the above post, I am still not clear on the part around exposure. Is it possible ...

What's the right way to use spot metering? Is it better to use in manual mode than one of the priority modes?
There's a question about when to use spot metering, but none that serves as a tutorial to ...

Have a look at these snaps. On the first one the church has the right exposure but the tree is too dark. On the other hand in the second one the tree is perfect but the church is too bright.

We don't get much snow in the UK, so I don't have much experience photographing it, and when I tried photographing falling snow last year I found it very hard to capture the snowflakes in the air — ...

I'm new at photography and I have taken some pictures where the subjects in the foreground are exposed correctly but the sky is very overexposed. What is the best way to handle it in post production?

I am shooting a time lapse and am doing some calculations beforehand to make sure I get everything right.
I am shooting a road trip from the west coast to the east coast and am planning to compress ...

For the exposure control function DSLRs there are specific shutter speeds available. For example there are 1/4, 1/100, 1/500. Why, even in high end DSLRs, is there no option to use a custom shutter ...

I have spent some time photographing landscapes with blue sky and white clouds, but the clouds always come out overexposed. I have tried different settings and still have the same result. What should ...

Ok, here's my doubt. Suppose I want to get a certain exposure for an image. Keeping the ISO constant, there are two tentative possibilities here:
Put the camera at f 1.4 (say) and at 1/1600 shutter ...
